UNITED STATES PATENT EEIcE.

IVILIIIABL CAREY, OF MONTREAL, CANADA, ASSIGNOR TO THE CAREY TIRE SEIVING MACHINE COMPANY, LIMITED, OF SAME PLACE.

SHOE-SEWING MACHINE.`

STECIFIGATION forming part of Letters Patent No. 559,771, dated May 5, 1896. Application led September 13, 1895. Serial llo. 562,464. (No model.)

To @ZZ wle-0m it may concern:

Beit known that I, WILLIAM CAREY, a citizen of the Dominion of Canada, residing at the city and district of Montreal, in the Province of Quebec, Canada, have invented certain neur and useful Improvements in Machin es for Uniting Soles and Uppers of Boots or Shoes; and I do hereby decla-re the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which vIt appertains to make and use the same.

My invention refers to an improvement in thc needle-bar and the mechanism that transmits a reciprocating motion to it in my machine already patented in the United States under No. 536,153 on March 26, 1895.

rlhis invention consists in the novel construction and combination of the parts herein after 'fully described and claimed.

Referring to the drawings, similar letters refer to similar parts throughout the several views.

Figure 1 is a vertical. section througlr the horn, showing the inside mechanism, Fig. 2 is a plan view showing the method of attaching my driving-lever t0 the screw that imparts it motion, and Fig. 3 is a horizontal section on line X X of Fig. l.

A is my ordinary horn, turning at a, while B is my ordinary screw, that rises and falls, as fully explained in my patent above referred to, my improvement consisting lin the needlebar C, which is a solid bar having a deep groove in its back to let my ordinarypinionshaft F pass, as shown on Fig. l at f, and the ordinaryneedle D is inserted in the usual manner in the head C. There the head is formed, two shoulders C4 are made, which servo to guide the needle-bar in its reciprocating motion, for as it ascends the shoulders O'l slide along the shoulders a', cast solid With the horn A, which, with the block a2, keep it in such a position that the needle practically travels vertically up and down, the block a2 being provided With a projection a3, (shown.

in dotted lines in Fig. 1,) that projects into the groove in the back of the needle-bar C and thus prevents any lateral motion.

To transmit the up-and-down or recipro- 5o eating motion of the screw B to the needlebar O, I use the lever of the first order, E, which is fulcrumed at c to the horn A and secured at its extremity e to the head of the screw B, as shown in Fig. 2, and has its other 5 5 extremity, e2, secured to the bottom portion of my needle-bar C, so that when the screuT B rises or falls the needle-bar C is made to fall or rise, thus transmitting to it its reciprocating motion. 6o

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s

l. In a sewing-machine for shoes, the combination, with a needle-bar provided with two shoulders at the front part of its upper end, and a groove in its rea-r part; of a horn provided With guides for the said shoulders to bear against and a projection engaging With the said groove and preventing lateral Inotion; and driving mechanism operating to reciprocate the said needle-bar in a vertical direction, substantially as set forth.

2. In a machine for uniting soles and uppers of boots and shoes, the combination of a solid needle-bar having a deep groove in its back and two guide-shoulders formed at its upper extremity where the head to carry the needle is made, a mechanism for transmitting a reciprocating motion to the above needlebar consisting in a lever of the first order joined at, one end to the needle-bar and at the other to a screw that rises and falls, with a screw I3, hornA having the guide-shoulders a' and guide-block ai substantially as described S5 and for the purposes set forth.

In testimony whereof I afx my signature in presence of two Witnesses.
